A case of huge retroperitoneal leiomyoma arising from the renal capsule is reported. A 56-year-old female was admitted with the complaint of microscopic hematuria. Abdominal ultrasonogram, CT-scan and MRI showed a huge solid mass in contact with the right kidney forming an indistinguishable plane between the tumor and the kidney. The tumor mass weighing 1,200g and measuring 16 x 14 x 9cm, was resected with the attached renal subcapsular tissue. The huge tumor was well-demarcated and composed of smooth muscle cells without mitotic figures, derived from the renal capsule. In addition, we discuss renal capsular tumors in general.
